'1 Claims. (01. 189-76) This invention has to do with slidably mounted tightly with the side walls of the channel consash of the type commonly used in the windows of verging a little toward the outer edge of the side railway cars and buses, and is particularly conrail. cerned with the means employed for effecting a After the sealing member I! has been applied to the flange l I of the side rail, frictional engage- 5 ment of the parts will prevent any endwise movement of the member relative to the flange while allowing the member to be pulled off edgewise without much difliculty whenever it is desired to renew the felt. If a more secure association 10 is desired, the sealing member i2 and the flange ll may be transfixed at one or more points with a rivet or other readily removable fastening device, but this is not necessary, as the resilient clamping action of the walls of the channel, trans- 15 mitted to the-flange through the interposed felt, produces a connection which is sufliciently secure to withstand the stresses to which a slidably mounted sash is subjected in ordinary'service.

The guide I3 is preferably, though not neces- 2U sarily, of resiliently expansible construction, one of the side walls l6 thereof being yieldably held in position by a spring strip i'l. When the felt covering ll absorbs moisture and swells in the guide, the walls ii of the guide will yield enough to compensate for the swelling, thereby maintaining a snugly weather-tight but readily slidable association between the side rail of the sash and the guide at all times.

The side rail fitting, hereinbefore referred to 30 as the sealing member I2, is preferably so proportioned with respect to the depth of the groove in the guide I3 as to contact with the back ll! of the guide while the projecting edges IQ of the side walls of the guide are still in spaced relation to the opposed edge portions of the side rail l0, thereby preventing any metal-to -metal contact between the sash and guide parts, which insulation feature not only cushions the sash against vibration but is of especial advantage in connec- 40 tion with sash made of aluminum and other metals subject to electrolytic action.

In Fig. 4 a somewhat similar sealing member, composed of an inwardly sprung sheet metal channel 20 and a felt wrapping 2| is shown applied directly to one of the side edges of a pane of glass 22, thereby providing a felt covered side rail for an otherwise rail-less sash.

We claim:

1. In sash construction, a side rail provided 50 with a rib, and a felt covered channel member fitted on the rib for sliding engagement with an the guides in which the latter is mounted.

The principal object of the invention is to provide an improved side rail structure which will give a smooth sliding fit with a guide and yet remain weather-tight under all the varying While the foregoing statements are indicative in a general way of the nature of the invention, other more specific objects and advantages will be apparent to those skilled in the art upon a full understanding of the novel structural features of the improved side rail fitting.

A preferred embodiment of the invention is presented herein for the purpose of exempliflcation, but it will of course be appreciated that the invention is susceptible of incorporation in other slightly modified structural forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is a fragmentary perspective view of one of the upper corners of a sash equipped with the improved side rail fitting of the invention, showing the sash slidably mounted in a guide;

Fig. 2 is a horizontal section through the side rail of the sash and the guide in which the fitting on the side rail is slidably mounted;

Fig. 3 is a horizontal section through the side rail and fitting, with the parts shown in separated relation; and

Fig. 4 is a fragmentary perspective view of a rail-less sash, showing the improved fitting applied directly to one of the side edges of a pane of glass.

As will be observed in the drawing, with reference particularly to Figs. 1 to 3 inclusive, each side rail ID of the sash is made of sheet metal and is provided at the center of its outer edge with an outwardly projecting flange II. The flange II project within and slidingly coact with a grooved guide I3.

The sealing member i2 is composed of a strip of felt H or other similar material and a sheet metal channel IS. The felt is folded about and within the channel, as shown in dotted lines in Fig. 3, and the channel, with the felt applied thereto, is sprung frictionally onto the flange ll, associated guide. the channel being preferably collapsed somewhat 2. In sash construction, the combination with prior to application in order to grip the flange II a laterally expanslble guide, of a sash having a 55 felt surfaced bearing portion for sliding coaction within the guide, the expansibility of the guide compensating automatically for either swelling or compacting of the felt, whereby to insure a smoothly sliding yet weather-tight engagement with the guide under either condition.

3. In sash construction, a sheet metal side rail provided at the center of its outer edge with an outwardly projecting flange, and a sealing member carried by the flange for slidingicoaction with an associated guide; said sealing member con sisting of a sheet metal channel and a strip of felt folded about and within the channel; and said channel with the felt thereon being sprung onto the flange in tight frictional engagement therewith.

4. In sash construction, a side rail provided at its outer edge with a relatively narrow outwardly projecting rib, and a sealing member fitted on the rib for sliding engagement with an associated guide, said sealing member consisting of a sheet metal channel and a strip of soft flexible material which is folded about and tucked into the channel, with the tucked-in portions of the same interposed between the side walls of the channel and the sides of the rib.

5. In sash construction, a side rail provided at its outer edge with a relatively narrow outwardly projecting rib, and a sealing member fitted on the rib for sliding engagement with an associated guide, said sealing member consisting of a sheet metal channel and a strip of soft flexible material which is folded about and tucked into the channel, with the tucked-in portions of the same interposed between the side walls of the channel and the sides of the rib, and with the back of the channel bowed and the side walls thereof converging toward the outer edge of the side rail.

6. In window construction, a sliding closure member, and metal channel members covered with felt or other suitable cushioning material sprung over opposite side edges of the closure member in tight frictional engagement with the latter for sliding engagement with associated guides.

7. In window construction, a sliding closure member, and metal channel members covered with felt or other suitable cushioning material sprung over opposite side edges of the closure member in tight frictional engagement with the latter for sliding engagement with associated guides, said covering material being in the form of strips which are folded about and tucked into the channel members, with the tucked-in portions interposed between the sides of the channel members and the side edges of the closure member.
